You should consider staying inside or limiting prolonged outdoor exertion when the outdoor Air Quality Index rises above 100, which is officially classified as unhealthy for sensitive groups such as children, the elderly, and individuals with asthma or heart conditions. When the AQI climbs past 150—categorized as unhealthy for everyone—even healthy adults should avoid strenuous outdoor activities and remain indoors with windows shut. Conversely, when outdoor pollution from wildfires or smog spikes into the very unhealthy or hazardous zones, staying indoors is crucial, but you must ensure your indoor space is equipped with running air purifiers featuring HEPA filters to prevent the stagnant outdoor pollution from seeping inside and accumulating.
